Product Description

Product Description

Introduction
    The Coolant Distribution Unit (CDU) is the core component of the water cooling system, responsible for efficiently distributing the coolant to meet various cooling needs. By integrating auxiliary monitoring and support devices, the CDU ensures stable operation of the system.
    It is mainly used for heat exchange control in liquid cooling systems, incorporating secondary side variable frequency circulating pumps, plate heat exchangers, electric control valves, temperature sensors, pressure sensors, filters, expansion tanks, flow meters, and online replenishment functions. The CDU is pre-installed and debugged at the factory, reducing on-site installation and commissioning work.

Performance Range

· Heat Transfer Capacity:350~1500kW


Features
· 10-inch Touch Screen: Multi-level authority control, easy to operate.
· Modular Design: Flexible expansion according to demand.
· High-Efficiency Variable Frequency Pump (Optional): Dual backup pumps automatically adjust flow rate, ensuring efficient operation.
· Dual Power Supply Backup (Optional): Enhances system reliability.
· Corrosion-Resistant Materials: Made with 304 stainless steel and above, ensuring long service life.
· Intelligent Control System: Includes temperature monitoring, secondary side temperature control, flow and differential pressure control, anti-condensation protection, and optional monitoring for conductivity, water turbidity, water hardness, and pH value.
· Ultra-Quiet Motor: Low noise and long service life, suitable for quiet environments.
· Standard Communication Protocol: Supports Modbus TCP, with comprehensive detection, alarm, and protection functions. Setup parameters are automatically protected, and operational parameters and alarm records are retained after power failure.
· Customizable Monitoring Protocol: Special format monitoring protocols can be customized according to customer requirements.
· Secondary Side Filtration Precision: Ultra-wide design range of 25~100μm, meeting various application needs.

Our Advantages
    With Venttk's innovative design, the CDU optimizes the performance and reliability of the water cooling system. It features six channels that connect the main circuit to the secondary water distributor of the water-cooled cabinet, reducing installation and production errors with the use of chucks and rubber hoses.
    Venttk's CDU incorporates a multi-stage centrifugal pump for industrial water circulation, ensuring efficient and reliable coolant flow. An integrated expansion tank compensates for temperature fluctuations, maintaining stable pressure levels and ensuring reliable system operation.
    To prevent issues such as oxidation corrosion, poor circulation, and cavitation of the circulation pump, the CDU includes an automatic air vent valve on the top of the makeup water tank/main pipeline, which promptly eliminates non-condensable gases from the system. 
    Additionally, the CDU is equipped with a 150μm filter in the main path to protect the quality of the coolant, ensuring the reliable and stable operation of the entire system.
    Choose Venttk's Coolant Distribution Unit (CDU) for a more efficient and reliable water cooling system.
